Résumé

Astrophytum mirum Halda & Panarotto has a stem morphology that agrees with that of an anomalous growth form of Astrophytum myriostigma subsp. tulense discovered in culture. The flower of A. mirum is indistinguishable from the flower of subsp. tulense. The type locality of A. mirum, now restricted to Mamaleón, Tamaulipas, is situated in the habitat of subsp. tulense. Alleged differences in seed size and root morphology between the two taxa are not confirmed as no examples were preserved with the type material. The conclusion is drawn that Astrophytum mirum Halda & Panarotto is a junior synonym of Astrophytum myriostigma subsp. tulense Kayser.
